Incident analysis

Gastroenterology & Hepatology of CNY was listed by Exitium ransomware, a group with 5 victims recorded in this database. The listing appeared on the group's leak site on April 14, 2026.

Gastroenterology & Hepatology of CNY is based in United States and operates in the Healthcare sector. United States ranks #1 worldwide for ransomware disclosures, with 10,212 victims in this database.

Sector context. Healthcare organisations are high-value ransomware targets because patient data is extremely sensitive, regulatory penalties for breaches are severe, and operational downtime can threaten patient safety — all factors that increase ransom payment pressure.

Exitium typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .
